Referring more particularly to the drawings and. in the presentexemplieation of the invention, the numeral 15 designates a portionof asuitable supporting frame or base upon which is mounted spaced walls16,'17, forming a casing for the segment 18, theteeth of which engage asuitable rack 19 which is operatively connected to the piston rod 20 ofthe pump 21, a portion of which latter is shown in Fig. 1 of thedrawings, so that'when the segment 18 is oscillated about its point ofpivotal support 22 the piston operating rac 19 will be raised andlowered. Motion may be imparted to the segment 18 preferably by means ofa gear 23 which .is journaled to a suitable casing 24, which latter issupported by the front face of the wall 16 of the segment casing, and asuitable operative connection 25 is arranged between the ear 23 and thesegment 18. otion may be transmitted to the gear 23 preferably by meansof a pulley 26 mounted upon a shaft 27, one end of which latter'may besu ported 'by the spaced walls 16 and 17 and tie other end by asuitabley bracket 28. One end of the shaft 27 extends through the se entcasing and secured for rotation i vic and is controlled by a lever 33which is fulcrumed intermediate its ends as at 34 (shown more clearly inFi 3 of the drawings) and one extremity hereof is pivotally connected tothe member 31 as at 35.

. The other extremity of the lever preferably ortion of the subjectmatter of applicationl erial No. 357,125, filed Februa 13,1907.

. Connected to the discharge out et 37 of the pump cylinder 21 (see Fig.l) is a discharge pipe 38 and communicatm with this pipe 38 at a pointremote from its discharge end is a pressure chamber 39 preferably 1n theform of a pi e which extends above pipe 38 and ma be eld in position inany desired or suita le manner, preferably by means of a bracket 40secured to the casing at apoint adjacent the end of the pipe 39. Whenthe piston rod 20 is operated, a portion of the liquid discharged fromthe pump vcylinder 21 will enter the chamber 39 to compress the airtherein so that the liquid vwill be forced out of the discharge openingof the pipe'r38 as the piston returns.v

The gear 23 is rotatably supported by the gear case 24 by means of theaxle 41, which 1s journaled -in said case,- and passing through the axle41 is a supplemental axle 42 Which `is secured for rotation with theaxle 41, and the forward. extremity thereof projects beyond the front ofthe gear case 24 andi's journaled in a suitable castin 43, which lattermay be secured in any desiredor suitable manner to the front of the gearcase 24. A gear wheel 44 is secured to the shaft 42 for rotationtherewith.l and said ves gear wheel meshes with a suitable gear wheel45, secured tothe shaft 46 of the cyclometer 47, which latter may be ofany ordinary or well known construction and is adapted to be operated bythe gear 23 through the medium ofthe beveled gear wheels 44, 45.

A disk 48 is rotatabl supported by the casting 43 and is locatepreferably beyond the journal of the axle 41 of the gear 23 and thisdisk is preferabl provided with a peripheral flange 49 w ich is providedwith worm teeth 50 adjacent the rear edge thereof, and mounted forrotation with the cyclometer shaft 46 is a worm screw or gear 51 whichmeshes with the worm teeth 50 (see Figs. 2 and 5)`so that when the gear23 is rotated the worm 51 will impart a rotary` motion to the disk 48and the worm gearing thus formed is so proportioned that onestopespecific construction of the clutch Loaepes @The disk 48 is alsoprovided with a series of notches 52 and an arm 53 is provided with adepending portion 53 adjacent one extremlty thereof adapted to be seatedwithin these notches.

Any suitable means may be provided for mounting the disk 48 for rotationand a suitn able and eiiicient means for accomplishing this purp'secomprises a hub 53", one ex tremlt-y of which is provided withperipheral screw threads adapted to engage corresponding threads in anaperture 54 of the casting 43. The other extremity of the hub isprovidedwith a shoulderl 55 which is adapted to enter a suitableaperture 56 in the disk 48 and a flange 57 isadapted to engage the faceof the disk to prevent displacement of the latter. The shoulder 55 andthe aperture 56 are of diameters greater than the diameter of theaperture 54in the casting 43 so that when theextremitv of the hub issecured into the casting, the shoulder 55 will project over the face ofthe casting to prevent the ange 57 from'binding the disk, which wouldhold the latter against free rotation.

A casing 58k is supported'byy the gear casing 24 to cover the casting43' and this casing 58 isV provided with a suitable aperture or openingthrough which the face of the disk 48 is exposed. A rin or plate 59 issecured to the casing 58 an surrounds the aperture therein and isjo adiameter slightly larger than the 'diamet'ero the disk, so that one'edgeof the ring will stand 1n close proximlty to the erip er of the disk.This ring 59 is provi ed withlya series of graduations 60, one of whichfis rovided for each ofthe notches 52 in the dis 48 and the graduationstiOare arranged in progressive order .with the zero graduationpreferably located to the left hand side of the disk and at a pointremote from the axle 41 of the gear 23.

'The hub 53b is rovided with a recess 61 (see Fig. 4) whic opens throughthe tcp thereof, and located l"wit-hin and assing through the recess 61isa screw or olt 62, the head of which is located within the recessandthe other extremity projects beyond the face of the disk 48. A.suitable o erating handie or knob 63 is secured to t e freeextremity'ofthe 'screw or bolt 62 and supported by this handle or knob63 is the .arm 53, and this arm is of such a len th that thereejextremity 'thereof -is adapte 'to enadjust'the arml 53 with relationto the disk '48 so as to seat the extremity thereof in another one ofthenotches 52, the resilient member 64 may be placed under tension, thatis, thehandle or knob 63 may bedrawn outwardly away from the face oflthe disk 48 l which will at the same time raise the arm l53 and when inthis position the arm 53 may be rotated about the face of the dial byturning the knob or handle upon the bolt or screw 62 as an axle untilthe extremit of the arm 53 has been placedv in position a ove thedesired notch 52 and when in this position the extremity of the arm willbe seated in the respective notch by the expansion of the resilientmember64 When'the knob or handle 63 is released.

A releasing member designated generally by the reference numeral 65e-nd`preferably in the form of al bell crank lever is pivotally supported asat 66 (see Fig. 2)' intermediate its lextremities to the casting 43l tothe rear of the disk 48. One of the arms 67 of the releasing member isprovided with a shoulder or offset portion 68 adjacent the freeextremity thereof. rA rod or bar 69 is pivotally connected by oneextremity as at 70 to the weighted extremity of the lever 33 (see Fig.3) The free end of this bar or rod is adapted to project through asuitable-'opening in the `casing 58 and is bent back upon itself as at7l to form a U-shaped extremity (see Fig. 6) and the extremity of theportion 71 thereofis adapted to engage and rest upon the shoulderor-projection 68 of the arm 67 of the releasing member 65 soY las toraise the weighted end of the lever `33 and lower the member 31 torelease the clutch mechanism 30 so that motion may be imparted from theshaft 27 to set the pump.

into operation. IfA desired, a suitable guide pin 72 may be providedwhich extendsl through the space formed between the body of the bar orrod 69 and its extremity 71 to been thus set the mechanism may be throwninto operation by `raising the lever 33 by 'means of handle 36, whichmovement will raise the extremity 71 of the bar or rod 69 to a positionto permit the shoulder or oi-v set portion 68 o n the arm67 of thereleasing member 65 to assume a posltlon (by means of gravity) withinthe path of the return movement of the extremity of the bar or rod andwhen the handle 36 is released the extremity will engage and restupon-the 'Shoulder or`projection 68. During the operation of the pumpthe disk 48 will be given one step o f rotation for each completerotation of the cyclometer shaft 46 and such rotation will be continueduntil the disk 48 has moved to such a positionas to bring the extremityof the arm 53, which is locked thereto, to the zero position or to the'zero graduation on the plate 59.

yIn order to prevent further operation of the mechanism when the arm anddisk have reached the zero position, suitable mechanism must be provided'for throwing the pumpout of operation. In order to accomplish thisresult suitable means will now be described for rocking the arm 67 ofthe release mechanism 65 about its point of pivotal support 66 to movethe projection or shoulder 68 away from the extremity 71 of the-bar orrod 69, which will permit the bar 69 to be lowered by means of theweighted arm 36, which movement will shift the member 31 to unlock theclutch mechanism 30.

Any suitable means may be provided for l this purpose but a simple andefficient mechanism will now be described.

A supplemental ldial or ratchet 73 is provided with a hub 74 and anoperating knob or handle 75 through which a suitable screw or bolt 76 isadapted to pass and by means of which latter the supplemental dial orindicator-may be rotatably supported or' secu'red to the casting 43.This. supplemental dial or indicator is located adjacent the zerograduation of the plate 59 and is provided with any desired number ofperipheral teeth 77 which extend over the plate 59 and the notches 52 inthe face of the disk and Wit-hin the path of movement of the extremityof the arm' 53, the hub 74 be-.

ing of sucha length to permit the teeth to assume such a position andthe ring 59 is preferably cut away as at 78 (see Fig. 6) to permit theteeth 77 to assume such a position withoutv materially increasing thediameter of the supplemental dial or ratchet. The other arm 79 of thereleasing member ,.65 is adapted to project over the hub 74 and isprovided with a depending hook-shaped portion 80, which is adaptedtostand behind the supplemental'dial or indicator 73 (see Fig. 6) and inclose proximity to the hub 74 thereof. v A

A split sleeve or holder 81 surrounds the hub 74 and is provided withprojecting ears 82, 83, one of which, preferably the ear 83. is somewhatlonger than the other ear and this sleeve or collar 81 is adapted to befrict-ionally secured to the hub 74 preferably by means of a screw orbolt 84 which passes through the ears 82 and 83 to draw the lattertogether and cause the sleeve to grip the 1 a hub. The sleeve is soarranged with respect to the hook-shaped portion 80'of the arm 79 of thereleasing member 65 that when the extremity 7l of the bar or rod 69rests upon the shoulder or projection 68 of the arm 67 ear S3 toward theextremity 8O ofthe arm 79 the ear will engage said extremity and tend toraise the same, thereby rocking/ the releasing member65 about its pointof pivotal support 66, to move the shoulder or projection 68 on the arm67 thereof away .from the extremity 71 of the bar or rod 69 to releasethe latter. Eacn of the teeth 77 of the supplemental dial or indicatoris provided with a graduation 85 and these graduations are arranged inprogressive order, in a clockwise direction.

The sleeve 81 is secured to the hub 74 in such a position that the ear83 thereof will ladiametrically opposite the zero'graduaion 85I on thesupplemental dial or indicator, that is, when the notch in which theextremity of the arm 53 is seated is opposite the zero graduation 60 ofthe plate 59, the ear 83 will engage extremity 8O and move the releasingmember in the manner just described. j j

Alocking paWl 86 (shown more clearly in Figs; 6 and 10 of the drawings)is pivotally supported as at 87 to the casting 43 .and is provided witha bearing 88 which extends through the casing 58, and rotatably mountedupon the bearing 88 is an antifriction roller 89 Which is adapted toengage between tWo of the teeth 77 of the supple-l mental dial orindicator 73, which latter is also located in front of the face of thecasing l58. A suitable yielding member 90, such as a coil spring or thelike, is provided to cngage thev dog 86 on one side of its pivot and anysuitable stationary portion of the mechanism, such as the casting 43,and Which tends to hold the anti-triction roller 89 in engagement withthe adjacent teeth of the supple mental dial or indicator. Thisanti-friction roller 89 is so arranged and the teeth 77 of thesupplemental dial or indicator are so disposed that When the arm 53 isout of engagement with one of the teeth, the zero tooth will assume aposition directly over the zero graduation on the plate 59, as shownmore clearly in Figs. 2 and 6 ofthe drawings, so that it will benecessary to im? part a partial rotation to the supplemental dial orindicator to uncover the zero graduation to permit the extremity of thearm 53 t'o register With the zero graduation in order to throw themechanism out of operation. This arrangement is provided in order thatthe ear 83 ofthe collar 81 Will normally knob or handle so as to brinstand out of engagement with the extremity of the releasing member 65 soas to permit the releasing member to assume a proper position to lockthe mechanism for operation and to permit the proper movement of thereleasing member for t is operation but when the extremit of the arm 53advances to the zero indicatlon on the plate 59, it will engage thetooth 77 of thesupplemental dial or indicator which projects over thezero indication just before the final step of rotation of the disk 48and the final step of rotation of the disk 48-will cause the extremityof the arm 53 to rotate the supplemental dial or indicator against thetension of the retaining anti-friction roller 89 as the extremity of thearm 53 moves to the zero position. The teeth 77 of the supplemental dialor indicator are preferably provided with inclined faces 91 which aredisposed at such an inclination that Vthis partial rotation of thesupplemental dial or indicator will not unseatthe anti-friction roller89 but will only move the anti-friction roller` a suiiicient distance torock the retaining dog S6 on its pivot 87 a short distance to permitthis necessary limited movement of the supplemental dial or indicator.

When it is desired to increase the number of strokes or limit of thepump, that is, increase the number of strokes or limit beyond the numberof strokes or limit indicated by the graduation on the plate 59, vvhichin the present exemplitication of the mventlon 1s a hundred gallons, allthat is necessary after the arm 53 has been properly adjusted is toimpart an axial rotation to the supplemental dial or indicator by, meansof the the tooth 77 thereof, which contains t e desired quantity to aposition directly over the zero graduation of the plate 59. It it isdesired to increase the number of strokes or limit from the numbernecessary to discharge one hundred gallons to a number necessary todischarge tWo hundred gallons, all that 1s necessary is to rotate thesupplemental dial or indicator so that the numeral 1 thereon assumes aposition over the zero graduation and likewise for any number ofgallons. If the numeral. 1 is over the zero graduation on the plate 59it will be apparent that one complete rotation ot the disk 48 Will causethe extremity of the arm 53 to move the supplemental dial or ratchet onestep of rotation, which step will cause the zero graduation thereon toassume a position over the zero graduation on the plate 59 if themachine is set for two hundred gallons, and this step of rotation Willnot throw the mechanism out of operation as the ear or projection 83 onthe collar 81 only moves one step nearer the hook-shaped extremit 80 ofthe releasing member 65. The dis 48 upon its next complete rotation willcause -the extremity of the arm 53 to engage the tooth 7 7 of thesupplemental dial or ratchet containing the zero graduation, which hasassumed aposition over the zero graduation n the plate 59, and thissecond step of rotation ofthe supplemental dial or ratchet will throwthe mechanism out of operation in the manner already set forth.

Thev casing 58 may be provided' with -a slot'92 (see Fig.' 2)', and ahandle or knob 93 may be connected to the releasing .meme ber 65 bymeans of a connecting portion or member 94 which, extends through theslot 92 and this knob or handle 93 is located onthe outside of thecasing 58'and serves as a means whereby the releasing member 65 maybetripped when desired, to throw the mechanism out of operation before thearm 53 reaches the zero position.

"# When it is desired to pump a quantity'ot liquid less than a hundredgallons, the arm 53. is set andlocked to thev disk 48 in the manneralready indicated and whenthe arm is moved out of the zero position thesupplemental dial or ratchet will be moved'by' the tension of the spring90 on retaining dog 86 so that the zero tooth will cover the zerograduation on the plate 59. Should .it v be desired to pump anotherquantity equal to the amount just pumped, it would be necessary tore-set the arm 53 4in the same manner. In order to permit thearm to bereadily re-set to pump the same uantity, and to dispense with thenecessity o a carefulfobservation and manipulation of the` arm, asuitable stop 95 may be provided. This stop is 'preferablyprovided withal dove-tailed base 96 adapted to move within a correspondingly shapedgroove 97 in the plate 59 and the dove-tailed base 96 mayA l96 so as toimpinge the bottom of the groove 97 to bind or lock the stop in anydesired position. -Pivotally sup Iorted bythe stop 1s an arm 99, theextremity 100 of which 1s adapted to project over the grooves or notches52 in the disk 48 so as to' stand within the path of movement of theextremity of thel arm 53 when the latter is moved in one direction.lThe` other ex-I tremity 101 ofthe arm is adapted toengage thebody ofthestop 95 so'as to. 'revent the arm from rocking in one direc ion, and ayielding membe'r 102, such's a coil spring orfthe like, is arrangedbetween the for normally holding 'the extremity'lOO in position.

The stopl 95 is adapted to be adjusted-so stop or notch opposite thegraduation denoting the desired amount of liquid and when it is securedin position by means of the screw 98, it will be apparent that when thearm 53 is rotated from the zero position or from the lposition shown inFig. '6 to the' right, it'will engage the extremity 100 of the arm l99,which latter will prevent a.

further movement of the arm 53 in the same direction. When the arm isthus adjusted and the'machine is set into operation, the arm will moveaway fromrthe stop and toward the zero position. When it is desired topump the same quantity the arm 53 is unlocked from the d'isk 48 andmoved away from the zero position and toward the stop until it engagesthe extremity 100,

thereby obviating the necessity of a 'careful manipulation of the arm.-Vihen the arm is moved in the-op ositedirection or from the positionshown 1n Figs. 1 and 2 toward the stop, the extremity thereof willengage the arm 99 and rock the latter about its point of pivotal support103 and against the tension of. the yielding member 102, which willpermit the extremity of the arm to pass the arm 99.

A measuring pump including a movable element, an indicatorcoperating with said element and having a series of characters arrangedto designate av certain limit, means whereby said element may beadjusted to' one of the characters, a supplemental element for extendingsaid limit and being provided with spaced projecting teeth, operatingmechanisnr` for returning the firstgsaid element from its adjustedposition,means whereby ,one of the teeth of the supplemental element maybe positioned j to be en aged 'and moved by the first vsaid elementefore the latter reaches a predetermined character on its returnmovement;y

said means comprising a member yieldingly f engagingbetween two of theteeth of the element under the control of the first said said. elementand provided with a plurality of characters arranged to designate acertain ble element, an indicator coperating with y limit, means wherebysaid element may be adjusted to one of the characters, a supplementalelement for extending the said limit and being provided with an inclinedportion, means .whereby said supplemental ele` ment may be adjustedindependently of the tirst said element, operatingmechanism forreturning the iirst said element from its ad justedy position, means forholding the supplemental element in such position that the `movementthereof lwill be compelled bythe first vsaid element before the latterreaches a lpredetermined character on' its said return movement, saidmeans comprising a yielding member engaging the said inclined portion ofthe s iupplemental element to cause a portion of said element tonormally assume a position in advance ofl the /said certain character,and means controlled by the movement of the supplemental element forrendering the operating mechanism inactive.

20. A measuring pump including any indicator, a disk coperatingtherewith, means also cooperating with the indicator for Iindicating apredetermined amo'unt within a certain limii, operating mechanism formoving the disk to move the said indicator from the indicated position,means operatively related y to the disk for extending the said limit,and means operatively related to the lastv said means for rendering theoperating mechanism inactive when the predetermined quantity has beenpumped, said.. means including a weighted handle, and said handle.serving as a means by which the mechanism may he placed in an activeposition.

2l. In a measuring pump, lthe combination of pump actuating means,tripping mechanism for stopping the actuating means when a predeterminedquantity has been Loa-6,053

pumped, embodying an element movable in a continuous orbit 1n unisonwith the pump actuating means, means including said actuating means forimparting such movement to said element, said tripping mechanismembodying a trip member whereby the said actuating means may becontrolled when said element reaches a predetermined point .in itsorbit, and means whereby said element may pass said point one or moretimes at will before the said trip member is actuated.

22. In combination in a. measuring pump, an indicator, a disk coperatingtherewith, means also coperating with the indicator for indicating apredetermined lamount within a certaln limit, operating mechanismincluding means for moving the disk to move the said indicator from theindicated position, means adapted to be set to extend -the said limit ofthe pump, and means cooperating with the last recited means forautomatically rendering the operating mechanism inactive when thepredetermined quantity has been discharged.

23. In combination in a measuring pump, an indicator, a disk coperatingwith the indicator, means alsocoperating with the'indicator forindicating a predetermined 'amount Within a certain limit, operatingmechanism including means for moving the disk to move the said indicatorfrom an indicating position, additional means adapted to be set at will,to extend the limit of the pump independently of the first recitedmeans, and means cooperating with the said additional means forautomatically rendering the operating mechanism,` inactive when thepredetermined quantity has been discharged.
